We're dividing 80495474 by 171 
The aim is to understand the frequency of 171 in 80495474.

Let's proceed to step 1:
171 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 171

Let's proceed to step 2:
171 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 171

Advancing to step 3:
When dividing 804 by 171, we get 4 with a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 684 from 804 leaves us with 120.
Append the next digit (9) from the dividend to 120 and continue with: 1209 / 171

Step 4:
171 goes into 1209 7 times with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
If we take 1197 away from 1209, we end up with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 171

Advancing to step 5:
171 can be fit into 125 0 times, resulting in a remainder of 125.
The number 0 becomes the next digit in our result. 
Result so far: 470.0
If we subtract 0 from 125, we get 125.
Grab the next digit (4) from the dividend, add it to 125, then carry on: 1254 / 171

Advancing to step 6:
171 can be fit into 1254 7 times, resulting in a remainder of 57.
The next digit of our result is 7. 
Result so far: 4707.0
The remainder is 57 after subtracting 1197 from 1254.
Include the next digit (7) from the dividend after 57, then repeat: 577 / 171

On to step 7:
When dividing 577 by 171, we get 3 with a remainder of 64.
The number 3 becomes the next digit in our result. 
Result so far: 47073.0
Subtract 513 from 577 to get 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 171

On to step 8:
When dividing 644 by 171, we get 3 with a remainder of 131.
Use 3 as the next digit of our solution. 
Result so far: 470733.0
Deduct 513 from 644 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 9:
171 goes into 1310 7 times with a remainder of 113.
The number 7 becomes the next digit in our result. 
Result so far: 470733.7
If we take 1197 away from 1310, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Step 10:
When dividing 1130 by 171, we get 6 with a remainder of 104.
Put 6 as the next digit of the answer. 
Result so far: 470733.76
The remainder is 104 after subtracting 1026 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 11:
The number 171 fits into 1040 6 times, leaving a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 470733.766
The remainder is 14 after subtracting 1026 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 470733.766, and the remainder is 0.0014.
